Method and system for security system tampering detection
First Claim
Patent Images
1. A method of indicating potential tampering with a security system component, the security system component including a camera lens, the method comprising:
- receiving an analytic alarm indicative of defocusing of the camera lens;
receiving data from an accelerometer;
receiving data from a light sensor; and
using a computing device to analyze the analytic alarm indicative of defocusing of the camera lens, the data from the accelerometer and the data from the light sensor to determine whether tampering of the security system component has occurred, the analysis includes determining whether a predetermined acceleration threshold has been met at approximately a same time as;
a change in lighting of a scene monitored by the camera lens; and
the defocusing of the camera lens; and
generating a qualified alarm signal when the analysis is indicative of tampering.

Abstract
A method and system for detecting tampering of a security system component is provided. An analytic alarm indicative of potential tampering with a security system component is received. Data from at least one sensor is received. A computing device is used to analyze the analytic alarm and the data from the at least one sensor to determine whether tampering of the security system component has occurred. A qualified alarm signal is generated when the analysis of the analytic alarm and the data from the at least one sensor is indicative of tampering.

10. A system for detecting tampering of a security system component, the system comprising:
-
an accelerometer affixed to the security system component, the accelerometer configured to measure acceleration of the security system component; a video analytic module, the video analytic module configured to generate an analytic alarm, the analytic alarm indicating potential tampering with the security system component; and a tampering monitor in communication with the accelerometer and the video analytic module, the tampering monitor configured to; receive acceleration data from the accelerometer; analyze the analytic alarm and the acceleration data to determine if the acceleration data meets a predefined acceleration threshold at approximately the same time as the generation of the analytic alarm; and generate a qualified alarm signal if the determination is made that the acceleration data meets the predefined acceleration threshold at approximately the same time as the generation of the analytic alarm. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
